Patented Apr. 2, 1918 Application filed March 20, 1917. Serial No. 156,169.

To all whom it may concern:

Be. it known that I, Orro nn Fnrns DION, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented a certain new and useful Improvement in Rag-Clipping Machines, of which the following 1s a specification.

The present invention relates to stripping machines adapted particularly for use in the preparation of rag material used in the manufacture of new material.

In the preparation of rag material such as woolens, for the manufacture 0 new woolen material, it is essential to removeall seams containing cotton and other fore1 substances which are undesirable, and t e present method of removing these cotton seams is to cut the same from the rag ma terial by hand.

It is an object of the present invention to provide a stripping machine by means of which the seams may be cut from the rag material quickly, and with but relatively small waste.

A further object of the present invention is to provide a relatively simply constructed and easily operated machine which requires but little practice in the operation thereof for applying the rag material thereto for the removal of the cotton seams.

The above, and various other objects and advantages of this invention will be in part described, and in part understood, from the following detailed description oi the present preferred embodiment, the same being illustrated in the accompanying drawings wherein:

Figure 1 is a transverse vertical section taken through a portion of a table havin the machine applied thereto.

Fig. 2 is a section taken transversely through one end of the machine on the line 2-2 of Fig. 1.

Fig. 3 is a similar view taken on the'line 3-3 of Fig. 1.

Fig. 4 isa detail enlarged sectional view taken longitudinally through one end of the machine.

Fig. 5 is an end elevation of the machine as applied to a table.

Fig. 6 is a detail side elevation of one of the stationary cutters or knives employed.

Fig. 7 is a transverse section taken through the stationary knife on the line 77 of The shafts 12 and 13 are connected to-.

gether by gear wheels 1 located preferably at one side of the table 10, the gear wheel 14 being intermeshed to turn the shafts 12 and 13 simultaneously and drive the same at the same rate of speed. The gear wheels 14 also cause'the shafts 12 and 13 to turn in opposite directions, and one of the shafts, such as the shaft 12, is provided with an extension 15 to which may be connected suitable driving mechanism for operating the machine. 3

The shaft 12 is provided, at opposite sides of the table 10, with pairs of feed rollers 16 and 17 which are suitably spaced-apart, and which cooperate with corresponding pairs of feed rollers 18 and 19 arranged upon the lower shaft 13, and which projects upwardly through suitable slots formed in the bed of the table 10. The tops of the rollers 18 and 19 are spaced slightly above the upper surface of the table 10 and are slightly spaced below the bottoms of the rollers 16 and 17 to receive cloth or the like between the super- .posed rolls. The shafts 12 and 13' are also provided, between the pairs of rolls 16 and 18, with superposed intermediate feeding rolls 20 and 21, the former being relatively small to provide a relatively large space between the rollers and thus accommodate ma-. terial folded or creased in several thicknesses.

The shaft 12 is provided with a pair of cutting disks 22 located at the opposite sides of the upper intermediate feeding roll 20, the cutter 22 being arranged between the feed rolls 16 and being of greater diameter than the same. The table is provided u on its upper face and immediately beneath t e cutting disks 22 with stationary cutting blades or knives 23, the latter being of semi-circular or segmental form and having an attaching flange 24 across the straight edge of each stationary knife. The flange 24 is provided with perforations 25 therethrough adapted to receive screws or the like for holding the stationary blades to the table 10. The ro- Jltary knives 22, and the stationary knives 23 are arranged in common vertical planes, and the rotary knives 22 are beveled at their marginal edges and at their outer opposite sides to interfit with the inner beveled marginal edges of the stationary blades 23. This arrangement is shown to advantage in Figs.

1 and 4 particularly.

The shaft 12 is also provided, between the rollers 17 with a rotary cutting blade or knife 26 which is beveled at opposite sides and which is of slightly greater diameter than the rollers 17 A substantially arcuate Igl'uard plate 27 extends across the tops of t e standards or 30 posts 11 and is curved downwardly toward the front of the machine and supported in such position by means of bracket arms or straps 28 which project forwardly from the standards 11.

In operation, rag material, such as a sleeve, may be folded or collapsed with the seams thereof arranged adjacent to the folds and run through the rollers 17 and 19 for cutting the sleeve into three sections by means of the blade. Each section is now flattened and fed to the rollers 16 and 18 with the intermediate seams thereof registering with the intermediate rollers 22 and 21. The feed rollers 16 and 18 draw the 5 flattened strip of material in between the rotary knives 22 and the stationary knives 23 to sever the material at opposite sides of the machine. The spacing apart of the feed rollers 20 and 21 is such as to receive the thickness of the seam therethrou h and feed it simultaneously with the fee ing of the outer portions of the strip.

It is of course understood that various portions ofgarments may be treated in substantially the same manner as above described by the use of this machine, and that the material is thus cut into strips and the seams removed therefrom.

Preferably, the fixed blades 23 are arranged in slightly ofi'set relation rearwardly of the machine from the vertical plane of the shafts 12 and 13 to engage the material in the rollers prior to the cutting action, the rollers thus holding the material taut and the cutting action tending to stretch the material and thus facilitate-the cutting of the same. i

It is of course understood that any num ber of feed rollers and cutters or knives may be used as is found convenient in the use of the machine without departing from the spirit of this invention, and various other modifications and changes :may be made in the details of construction of the above specifically described embodiment without departing from the spirit of the lnvention, and being restricted only by the scope of the following claims.

I claim 1. In a strip ing machine, the combination of a pair of vertically spaced apart connected shafts adapted to turn in opposite directions, spaced-apart pairs of feed rollers mounted on the shafts, a pair of spaced apart intermediate feed rollers arranged between said pairs of rollers, a pair of cutting disks arranged upon one of the shafts at the opposite si es of the intermediate rollers, and a pair of stationa cutters arranged between said pairs of eed rollers at the opposite sides of the intermediate rollers for cooperation with the rotary cutters.
